Work through the cost and budget decision
Compare a personal loan and credit card using the same amount of debt paid off, realistic payment budget, fees and payoff date. A fixed loan can make the end date clearer, but a fee can offset a lower interest rate. A promotional card works differently: the balance and transfer fee must fit the promotional payoff plan, and the actual post-promotion terms matter.
Which costs less when both are repaid in 36 months?
This invented example starts with $9,000 owed. Card interest is fixed at 24% annually, charged monthly, with no new spending or other fee. The loan supplies $9,000 net to pay that balance after a 4% fee on gross principal is withheld, so its principal is $9,375. Its annual note rate is 15%; the fee-inclusive APR would be a different figure. The comparison fixes the payoff horizon first.
What changes if the budget stays at $350 instead?
The card payment here is a fixed $350 budget, not the issuer’s changing minimum. The loan path assumes permitted extra principal payments without a charge. These assumptions should be checked before using the result.
What must be true for a 0% transfer to work?
Assume an invented 0% promotion lasting 18 monthly payment periods and a 5% balance-transfer fee added to $9,000. The starting balance is $9,450 and requires $525 per month to clear in time. Repayment is $9,450 only if the promotional terms apply throughout and the full balance is cleared without other charges. This is not an available offer. Eligibility, transfer limits, deadlines, missed-payment rules and later APR must come from the actual agreement.
At a $350 budget, paying 18 installments totals $6,300 and leaves $3,150 when that modeled promotion ends. No later interest is forecast because the later APR is unknown. Do not treat a 0% headline as a completed payoff plan. The CFPB explains credit-card grace periods and purchase-interest risks when carrying balances; avoid mixing new purchases into a balance-transfer comparison.
How are these comparisons reproduced?
Version 1.0, October 29,2026. Equal-horizon payment is M=P*r/(1-(1+r)^(-n)). Use P=9000 for the card, P=9000/0.96 for the fee-withheld loan, and annual note rate/1200 for r. For the fixed-budget paths, each month add balance*r interest, pay the lesser of $350 or balance plus interest, and repeat until zero. Calculate full precision; round displays only. No daily interest, changing rates, other fees, rewards, additional purchases or missed payments. Promotional payment is 9000*1.05/18.
